Question

Two dice are thrown simultaneously 525 times. Each time the sum of two numbers appearing on

their top is noted and recorded as:

Sum 2 3 4 5 6 7 8 9 10 11 12 Total

Frequency 24 25 62 45 42 70 70 63 46 28 50 525

If the dice are thrown once more, what is the probability of getting a sum:

(i) Of 9

(ii) Less than or equal to 6

(iii) Which is a multiple of 4

(iv) Which is a perfect square.

(v) A prime number​

Answer 1

Answer:

Correct option is

C

0.254

If we rolled dice around 500 times then it can be considered as its expected outcome.

Hence,

Probability of obtaining between 8 and 12 as sum = 53 + 46 +28/500= 0.254
